Meaning "to honor very highly" is attested from 1590s; weakened sense of "to be very fond of" emerged by 1880s. Related: Adored; adoring.
to worship; to express reverence and homage. The forms of adoration among the Jews were putting off the shoes (Ex. 3:5; Josh. 5:15), and prostration (Gen. 17:3; Ps. 95:6; Isa. 44:15, 17, 19; 46:6). To "kiss the Son" in Ps. 2:12 is to adore and worship him. (See Dan. 3:5, 6.) The word itself does not occur in Scripture.
